Need someone with obdii scanner/ help get her started

[Jim]

That's great progress!!

...but I'm scratching my head - what did you change from no-run to run? It seemed like you weren't getting spark...

[4x4JeePmaNthINg]

Your question is valid, idk really. I re indexed the distributor for the 3rd time. I had a good laugh once I found i struggled this last time from using the 2.5 guide hole instead of the 4.0, the other times were far easier when done right. removed and cleaned grounds again. The CEL disappeared and now these other codes exist.
I had pulled the coil to test last week after no spark with the test light.( im still uncertain if a test light would be worked for high output), reinstalled the ignition coil and tested spark with a plug, which it had this time.
I'm going to remove the ignition coil again and re test it in warmer conditions, I'm not so confident that it is 100% ok.


Now to tear into the TPS again, it's running, but I'm not out of the woods yet.

[4x4JeePmaNthINg]

On 20v dc I'm getting .71v resting/idle, 3.90v at wide open throttle. It needs to be higher than .26 and lower than 4.49v so it seems good.

Now I'm lost, any ideas?

[Jim]

I don't know TPS's much - but when mine went it seemed to have a "dead spot". Is yours consistent (gradual change from low to high) with voltage through the range? It doesn't have any drop or spike through the range?

[4x4JeePmaNthINg]

Yes it's smooth, I'm trying two more tests that I've read about. On pins1&3

[JandDGreens]

Anything new to report?

[4x4JeePmaNthINg]

Ha, right now this thing is whipping my butt. She idles fine until at operating temp, then starts sputtering terribly.

[Jim]

How much is a TPS? (just replace it and cross fingers) If mine's the same you could borrow it for testing.

Strobe light shows timing is correct, yes?

[4x4JeePmaNthINg]

Haven't used any strobe deal?

I don't understand how it runs fine until warmed up. Can you rent a timing strobe and what should it read? I believe Mopar TPS is 87$ ish, 02 ntk brand 35$. I'm going to attempt a vac leak test with propane and a diy smoke machine test also for vac leaks.

Another jeeper asked if a tooth on the distributor could be off, I don't think it will fit the retaining clip if it were, would it?
O2s are Bosch and were replaced few years ago, others say these don't work well in 4.0s??? Hypoid, they read, but obviously there's something not right vac leak or other.

Cap, rotor, napa echlin new, New plugs Autolite APP985 4.0 recommended, injectors are BWD 4 hole they were bought new a few years ago and ohm test good. Fuel pump Bosch few years old.
IAC,MAP stock
TPS napa I think, it's my 3rd,
Likely to put Mopar in just in case.
Throttle body stock with fel-pro gasket
New motor with banks revolver header & gasket, 99 intake

I'm try I'm trying these tests and inquiring for more knowledgeable hands on help to get this thing running. Ill pay my way to get my wheels back, please P.M. me if yiur quite confidant we can fix this.I need this vehicle back on the road, it's currently in my garage and ide Really not like to tow it somewhere.

I'm humbly for diagnosing anything I'm not considering, keep throwing ideas if you all have them.

Thank you all very much

Mike's on it!

If you wish my hand or any tool I might have - willing to assist.

[4x4JeePmaNthINg]

No hood vents mike, first tps went with the event I'm believing to taken the first motor out, threw a cheapo replacement on to get it started back then. Cheapo got wet and instantly wasn't having it so I put a napa one on a couple years ago.

Is there anything you would want me to have on hand Mike?

[Patrolman]

Congrats on getting it running. Sounds like significant progress!

I have a 60K BTU kerosene unit avail...

[4x4JeePmaNthINg]

No but I have one of those two dish looking propane heaters

[Hypoid]

I have a propane heater that looks and sounds like a jet engine, and a lot of propane. Won't hurt to load them also.

[4x4JeePmaNthINg]

No complaints here haha, were just lucky it's not minus whatever out tomorrow!

[Jim]

`curious to what happened...

[4x4JeePmaNthINg]

Well Jim. I don't want to muddy Mike's follow up. He was very thorough and we found a lot of interesting information. I will say she's running! BUT I tried to move her just now and I heard a buzzing from the transmission while shifting back up to park. Fluid was low so I topped that off once at temp. I tried shifting twice before checking fluid, just ran through the gears as it was running. After,
I adjusted the kickown cable, but I don't know what in the world this noise is!!! Haven't tried after adding fluid, I need info lol. Ugh this never ends, if only ide have thought of trying to move her while you were here Mike, you KNOW your stuff!!! I can't thank you enough for the help and the knowledge base you just can't read about, it comes with years turning the wrenches!!!.

Thank you again Sir.

Ideas? I do Not want to damage anything. Perhaps I've missed a step after reinstalling the trans shift linkage??

I have looked as close to the bell housing as possible, I can't see anything binding, but I can't see the very top either.
